26. Please answer literal D A pizza restaurant delivers pizzas throughout its local market area at no charge to the customer. However, customers often tip the driver. The owner is interested in estimating the mean tip income per delivery. To do this, she hasselected a simple random sample of 12 deliveries and has recorded the tips that the drivers received. These data are shown below. Complete parts a through d.$2.00$0.50$2.75$1.75$1.25$1.75$2.00 D$2.50$1.50$1.75$2.00$1.00V t-distributionO uniform distributionbinomial distributionc. Referring to part b, what assumption is required to use the specified distribution to obtain the critical value? Develop a box and whisker plot to illustrate whether this assumption seems to be reasonably satisfied.What assumption is required to use the specified distribution to obtain the critical value?O A. The population distribution is exactly symmetrical.O B. The population distribution is uniformly distributed.O C. The sample size is at least 30.YD.The population distribution is approximately normal. d. Referring to parts b and c, construct and interpret the 99% confidence interval estimate for the population mean.The 99% confidence interval estimate is S(Round to two decimal places as needed. Use ascending order.)
